rxrnwnrne MACHINE.'

The present invention relates to casings for typewriting machines, and more particularly to casings in which machines of the so-called portable class are]V carried from 5 place to place by a handle on the casing.

Such casings are ordinarily in two parts, to wit, a part which comprises one wall of the casing and which serves as a base-board forthe machine, and a cover-portion which fio defines the chamber within which the machine is set and which is placeable over the base-board and attachable thereto. Whereas .the baseboard may serve as 'the support for the machine in the operation thereof, it is oft-en desirable to disconnect the machine from the board and employ another supportV Other features'and advantages will here` inafter appear. In the accompanying drawings,

Figure 1 is a view, in lcross-section, substantially on the line 1-.1 of Figure 2, through the assembled casing and machine. Figure 2 :is a top plan view on the line 2-2 of Figure 1. ,Y l

Themachine comprises a main frame 10 set within, and secured by screws 11 to, an outer ornamental frame 12. The main frame comprises side pieces 13, connected Vby front and rear cross-pieces 14 andv 15. Mounted for up-and-down mov-ement in the main frame, between case positions, is ya shift-- frame 16; the side plates 17 of which are connected at the rear by a cross-piece 181 and forward thereof by a cross-piece 19. rlhe cross-pieces 18 and 19 have rails ,20 and 21 formed, respectively, thereon, to serve as runways for the platen-carriage. The platen-carriage comprises side plates 22, in which the platen 23 is journaled, connected at the rear. by a cross-piece 24 and at the lower portions thereofby a cross-piece 25. The rear cross-piece 24 carries a bracket 26, in which is journaled a roll 27 which rides on the rail 20. The lower cross-piece 25 is channeled at 28 to receive rollers 29,' by

means of which the same, is supported on'the l .runway 21. A roller 30,'carried by anl arm 31 attached to the cross-,piece 25, engagest-he underside of the rail 21 to hold the forward 60 part of the carriage to the rail. A lip'32, on the bracket 26, underlies the rail 20 to :hold the rear of the carriage to vthat rail. The carriage is'provided with the usual papertable and apron-piece 33which extends from the upper rear portion of the carriage down around and to the front of the platen.

The lower edges of the plates 13 of the main frame have ianges34v offset inward therefrom. Frontand rearfeet 35 van`dv36, 70 respectively, are secured to each s of' the flanges 34. For securing thev feet, the same have theirunder faces countersunk, as at 37,

lto receive the heads 38 of screws 39, which pass upward through the feet and'thread into the flanges 34. The feet'have heads or enlargements 40 attheir lowerY extremities, defined by yshoulders 45. These heads' rest Secured at their front and rearfends to the upper face ofthe base-b'oard,bymeans ofscrews 47, one at each .side 'of' the base-board, in alignment with thefeet of the'typewriting machine, are anchor-plates 48. Between vthe lines 49 and 50 (see Figure 2), .the anchor-plates lie flat against the base-board. Beyond the linesf49 and 50 (as'shown in Figure 2) the anchorplates are odset upward, as shown in Figure 1,' to provide horizontal elevated portions 51 and 52, respectively, at the front and rear I of the plates. vThe rear portions of the plates are enlarged, as at 53, and these enlargef ments" have openings V54 therethrough, of a size to receivel the heads 40 of the rear feet the machineV to the baseboard, the machine is set flatl on vthebase-board in such position that the heads 40,0f the rear feet ofthe machine are within the openings 54 in the anchor-plates. The machineis then forced rearward on the base-board so as to cause the heads 4() of the rear feet to pass under therear elevated portions 52 of the plates. In 'this operation, the narrower portions 55 105 in the elevated rear portions 52 of the plates;

vthe openings 56 being extensions of the openings 54, constrictedto prevent .upward movement therethrough' of the heads 40 of the feet when the machine shall have been thus thrust rearward. The shoulders or upward effects 57 ,f which deiine therein" edges of the elevated plate-portions 52, may serve as stops the board, one at each side of the same;

to determine the extent of rearward movement of the machine on the base-board and to define the'true centered position of the machine.

When the machine has been placed and thrust rearward, as just described, certain screw-holes 58 in the flanges 34, near the forward ends ot the latter, register with certain other screw-holes 59 in the baseboard. Blocks 60, having screw-passages therethrough, are set into openings 6l in the forward elevated portions 5l ot the anchorplates, and rest upon the base-board, as shown in Figure l, with the screw-passages therethrough in registration with lthe holes `58 and 59.A The raised portions 5l have a rounded outer contour and are odset outwardly from the plane of aligned front and rear feet so that the tangential planes oi the raised portions and adjacent front feet tlld ,to overlap. Screws 62 are then passed down through the flanges 34, through the blocks 60 and base-board 46, to be threaded into and locked by nuts 63 set-intok countersinlrs 64 in the under face oi the base-board. l/Vhiell the blocks 6 0 have thus been set in the openings 6l in the anchor-plates and secured to the `machine and to the base-board, the V forward elevated and rounded portions 5l of the anchor-plates will prevent forward or sidewise movement of the machine to release the rear feet thereof from the rear elevated portions 52 ot the anchor-plates; and the screws 62 having been tightened, upward movement of the front part of the machine, Sufficient to clear the blocks 60 from the elevated portions 51 ot the anchorplates, is prevented. The height of the blocks 60 is such as substantially to lill the `space between the upper face of the baseboard and the lower 'faces of the flanges 34, and, therefore, the blocks cannot be cleared ot the anchor-plates by upward shift of the blocks on their retaining screws 62, The .blocks 60, as well as the feet or the typewriter, may be ot rubber.

lt'will be noted that one and the same anchor-plate or piece comprises the means for holding both the rear and front i'eet of the machine at one side ot' the latter; and that such anchor-plate may consist of a single piece of sheet-metal formed in one or more stamping and bending operations.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, l claim: Y
